IMPROVEMENT IN TIRE-HEATERS.

Specification forming part of Letters Patent N o. 19l,3l0, dated May 29,1877; application filed April 16, 1877.

To all whom it may concern.-

Be it known that I, PHILIP WARD OASSIL, of New Athens, in the county ofHarrison and State of Ohio, have invented a new and useful Improvementin Tire-Heater, of which the following is a specification Figure 1 is afront view of my improved tire-heater, one of the doors being shownopen. Fig. 2 is a vertical section of the same, taken through the line:0 m, Fig. 1. Fig. 3 shows a modification of the same. Fig. 4 is adetail section, taken through the line y y, Fig. 3.

Similar letters of reference indicate corresponding parts.

The invention will first be described in connection with the drawing,and then pointed out in the claim.

A represents the furnace or fire-box, to the top of which is secured thering heating-chamber. The heating-chamber consists of the ring-plate B,having a ring-flange or rim, 0, formed around its outer edge.

To the ring-plate B are attached the outer end of a number of arms, D,the inner ends of which meet in the center of the ring-plate B, and havea journal, E, attached to them.

The journal E may be hollow or solid, and upon it is placed a hub, F, towhich are attached a number of radial arms, G, to the outer ends ofwhich is attached a rim, H. The rim H fits against the inner part of thering-plate B, and forms the inner wall of the heating-chamber.

The front of the heating-chamber is formed of two half-ring plates, I,which are hinged at the middle parts of their outer or convex edges tothe outer rim 0, so that they may be swung back to allow the tires to bereadily put in and taken out. The doors I are secured in place, whenclosed, by bolts J, buttons K, or other convenient fastenings.

To the convex side of the inner rim H are attached slotted plates L, toserve as racks to receive the different-sized tires, and support them sothat the fire may circulate all around them.

The rim H may be made in sections of such a length that their adjacentends will overlap each other, as shown in Fig. 3, and the arms G may bemade in two parts, overlapping and sliding upon each other, so that therim H may be expanded or contracted as more or fewer tires are to beheated at a time, to economize fuel.

One part of the arms G should have its edges bent over to form groovesto receive the edges of the other part, and the two parts have a numberof holes formed through them to receive the pins M by which they aresecured in place when adjusted.

To the outer parts of the adjustable arms G are attached handles N forconvenience in adjusting them.

By this construction, by turning the rim H all parts of the tires willbe brought direct- 1y over the hottest part of the fire, so that thesaid tires will be heated and will expand evenly.

Having thus described my invention, I-

claim as new and desire to secure by Letters Patent- The combination ofthe racks L with the re volving inner rim H of a tire-heating chamber,substantially as herein shown and (is scribed.
